Reaction Steps

A solution of (S)-tert-butyl 3-((8-chloro-3-(5-oxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)isoquinolin-1-yl)amino)pyrrolidine-1-carboxylate (170 mg, 0.52 mmol) in HCl/EtOAc (10 mL) was stirred at RT for 2 hours. The reaction mixture was subsequently concentrated in vacuo to give an HCl salt of the title compound (160 mg, 100%). 1H NMR (400 MHz, DMSO-d6) δ ppm 11.90 (s, 1H), 11.85 (s, 1H), 9.134 (s, 2H), 7.86-7.84 (dd, J1=2.8 Hz, J2=6.8 Hz, 1H), 7.64-7.62 (m, 3H), 7.57-7.56 (d, J=6.4 Hz, 1H), 5.0 (s, 1H), 3.65-3.60 (m, 1H), 3.24-3.21 (m, 2H), 2.40-2.36 (m, 1H), 2.11-2.07 (m, 1H).
